Is Making the Homeless Arm Wrestle for Cash Classy or Trashy?

Watch as a pair of homeless men square off in an arm wrestling battle, with the winner getting $100. When the winner is crowned, you may be surprised by what he does, proving once again there's more to the homeless than what we think we know.

Was this a nice gesture by the guys who put on the contest or was it demeaning to the homeless men who participated (especially that line about the loser going "home empty-handed")?
